- Title: Connecting steady-states of driven-dissipative photonic lattices with
spontaneous collective emission phenomena
- Authors: Alejandro Gonz\'alez-Tudela
- Abstract summary: We use intuition to predict the formation of non-trivial photonic steady-states in one and two dimensions.
We show that subradiant emitter configurations are linked to the emergence of steady-state light-localization in the driven-dissipative setting.
These results shed light on the recently reported optically-defined cavities in polaritonic lattices.

- Abstract: Recent experimental advances enable the fabrication of photonic lattices in
which the light propagates with non-trivial energy dispersions. When interfaced
with quantum emitters, such systems yield strong collective spontaneous
emission phenomena, such as perfect sub-radiance, in which the decay into the
bath is completely suppressed, forming bound-states-in-the-continuum. Since
such photonic lattices are generally lossy, an alternative way of probing them
consists in coherently driving them to an steady-state from which
photoluminescence can be extracted. Here, we formalize connections between
these two seemingly different situations and use that intuition to predict the
formation of non-trivial photonic steady-states in one and two dimensions. In
particular, we show that subradiant emitter configurations are linked to the
emergence of steady-state light-localization in the driven-dissipative setting,
in which the light features the same form than the spontaneously formed
bound-states-in-the-continuum. Besides, we also find configurations which leads
to the opposite behaviour, an anti-localization of light, that is, it
distributes over all the system except for the region defined between the
driving lasers. These results shed light on the recently reported
optically-defined cavities in polaritonic lattices, and can guide further
experimental studies.

We study subradiance in a Bose-Einstein condensate positioned at the mode crossing of two optical cavities.
metastable density structures that suppress emission into one cavity mode prevent relaxation to the stationary, superradiant grating.
We reproduce these dynamics by a quantum mean field model, suggesting that subradiance shares characteristics with quasi-stationary states predicted in other long-range interacting systems.

Spontaneous emission is a fundamental out-of-equilibrium process in which an excited quantum emitter relaxes to the ground state due to quantum fluctuations.
One way to modify these photon-mediated interactions is to alter the dipole radiation patterns of the emitter, e.g., by placing photonic crystals near them.
Our study delves into the interaction between these directional emission patterns and the aforementioned variables, revealing the untapped potential to fine-tune collective quantum optical phenomena.
